Our last two Z97 reviews involved some petite motherboards, so it’s time to go all-out – something GIGABYTE’s Z97X-Gaming G1 WIFI-BK helps us pull off. Its name implies that gamers are the target here, and as you’d expect from its $350 price tag, it’s packed with features. What more reason do you need to read? Come on in.
From a performance perspective, we feel that motherboard benchmarking is useless. It’s the motherboard’s job to allow all of the installed hardware to operate at its full potential, so in theory, a $100 option shouldn’t be much (or any) slower than a $300 one. The differences in price instead comes down to the quality of the onboard components and other features.
So why do it at all? It’s because it’s important to make sure that the board we’re dealing with doesn’t lack in one particular area versus the rest. If board A performs 2% slower than board B in PCMark, for example, that’s of no concern to us – random benchmark variance is a fact of life. However, if one board consistently performs weaker than the rest, that’s worthy of note – it could suggest that weaker components have been used which do not allow the hardware to operate at its full potential.
Please bear this in mind when perusing our results. Just because a board under-performs in a single test, it doesn’t mean anything in regards to its quality as a whole. Our ultimate goal here is to make sure that each board we test performs as we’d expect across the gamut of scenarios we pit them against.

Note: ASUS’ Z97I-PLUS was tested with its ‘MultiCore Enhancement’ option left enabled. This means that the CPU was clock-boosted, which will result in improved performance over MSI’s Z97I Gaming AC and GIGABYTE’s Z97X-Gaming G1, both of which ran at absolute stock, CPU-wise. Also, because the design of the MSI board prevented me from using the same tall memory sticks I had used for testing the the other boards with, the specs are dissimilar. The MSI board was tested with 8GB of memory spec’d at DDR3-1866 – a stark contrast to the 16GB of DDR3-2133 we normally use. A difference in hardware like this isn’t ideal, but this particular motherboard forced my hand. None of our tests exhaust 8GB of memory, so the sole difference here will be via the frequency.

Increasing the BCLK value is one way that vendors could sneak in some higher-than-stock performance numbers, so after letting the test bench sit idle for a couple of minutes, we look at the current BCLK value as according to CPU-Z.

All boards perform well here, with ASUS getting the slight edge that we expected it would. Interestingly, though, while the GIGABYTE and MSI boards go head-to-head in Home and Work, the big G comes close to the ASUS in Creative.

ASUS takes the lead once again, but as usual, the performance is so close that it’s negligable.
Rendering & Image Manipulation
Writing files to disk or reading a website doesn’t do much to exercise our CPU, so for that, we turn to a few common scenarios – image editing, video rendering, music conversion, and 3D rendering.

It’s interesting here that despite ASUS having a clock boost, it matched up well with GIGABYTE which didn’t auto-OC itself. As for MSI, even though memory has no big say in the Arithmetic test, it fell behind the other two boards here.
In the end, there’s usually a trade-off between boards somewhere in testing, and there’s no exception here. Overall, they all perform well.
